Question:

Why do rainbows occur?

Julia G.
Answer:

It is common knowledge that if it is raining but also sunny a rainbow can appear. This is due to the rays of the sun hitting the raindrops in a certain angle that the white light from the sun reflects and disperses into different colors in the sky. Because of this dispersion, you are able to see each color individually, creating a rainbow.
